Problems solved by technology

[0005] For sensors using the conductometric method, the electrodes are generally in contact with the measured substance. When the research object has a lot of non-conductive substances, the measurement electrodes are in contact with the non-conductive substances, causing the measurement electrodes to float, which easily leads to saturation of the resistance/conductance measurement circuit. , ...

Embodiment Construction

[0021] The two-phase flow split-phase holdup impedance sensor and its structural parameter optimization method of the present invention will be described in conjunction with the accompanying drawings and embodiments.

[0022] As shown in Figures 1 and 2, in the cross-section of the two-phase flow split-phase holdup impedance sensor, its structure is composed of three layers. The outer structural layer is a metal shielding layer 1, which plays a shielding role. When the inner structural strength is not enough , the thickness can be adjusted to play the role of structural support, pressure resistance, etc., the middle layer structure layer is the insulating material layer 2, which isolates the excitation electrode 4 and the measurement electrode 5 from the metal shielding layer 1, and the inner layer structure layer is the insulating tube layer 3 And the excitation electrode 4 and the measurement electrode 5 attached to its outer wall, in the axial direction, when the excitation ...

Abstract

An impedance transducer of mobile phase content in two-phase is prepared for applying metal shielding layer as external layer for enabling to regulate thickness to support structure, applying insulation material layer as intermediate layer for isolating excitation electrode and measurement electrode from metal shielding layer, applying insulation pipe layer with excitation electrode and measurement electrode as internal layer and setting two said electrodes on pipe wall of insulation pipe layer radially and symmetrically in mode of 180degree -angle spiral distribution. The method for optimizing structure parameter of said transducer is also disclosed.

Description

technical field [0001] The invention relates to a detection device and its application, in particular to a two-phase flow split-phase holdup impedance sensor and an optimization method for its structural parameters. Background technique [0002] Phase holdup is an important parameter for online real-time measurement of two-phase flow, which is of great significance in industrial production and oil transportation. [0003] There are many methods for measuring phase concentration, such as electrical method (such as patent: JP2007033062-A, Impedance type practical electric void fraction meter for measuring water flow trial, measures average void fraction of two phases of flow of water in instant, without being based on water quality, usingrod-shaped assembly), acoustic method (GB2120791, Microwave gas-liquid voidfraction meter), optical method (such as patent: JP9257704, Void Meter), ray method (JP57175247, Radiation void factor meter, US4282435, Mono-energetic neutron void met...
